HAY-PRESS.

To all whom it may concern:

Be it known that I, ERNEsT L. VVETZIG, a citizen of the United States, and resident of Clint, in the county of El Paso, State of Texas, have invented a new and useful Improvement in Hay-Presses, of which the following is a specification.

My invention is an improvement in hay presses, and has for its object the provision of means in a press of the character specified for reciprocating the plunger at regular intervals, and wherein the connection between the operating means and the plunger is of a character to transmit a high proportion of the power of the motor with a long working stroke and a quick return.

In the drawings: Figure 1 is a side view of the improvement; Fig. 2 is a plan view; Figs. 3 and 4 are sections on the lines 3-3 and 4:4:, respectively, of Fig. 1; and Fig. 5 is an enlarged detail view of a portion of the pressing chamber. 7

The present embodiment of the invention comprises a frame composed of upper and lower pairs of longitudinal bars 1 and 2, of angle material, connected at one end by plates 3 to form a casing or pressing chamher for the material to be pressed. The bars 1 are of less length than the bars 2, and extensions 1 are arranged in alinement with the said bars 1 and are secured thereto in a manner to be presently described.

A yoke or bail has its body 4 journaled in bearings 5 on the under faces of bars 2,

and the arms 4 of the yoke or bail are passed through openings in the ends of a rod 6 journaled in bearings 8 on the extensions 1 and handle nuts 7 are threaded onto the ends of the arms above the rod.

An angle plate 9 is arranged transversely of the bars 1 adjacent to the extensions 1*, and a similar plate 10 is arranged transversely of the extensions near the plate 9. Each plate has one of its portions secured to the bars 1 or 1 and the other portion extending vertically, and bars 11 and 12 are arranged on the inner faces of plates 9 and 10, respectively.

The vertical portions of plates 9 and 10 and bars 11 and 12 are perforated at spaced intervals,the perforations of the respective plates and bars being in alinement, and bolts 13 are passed through the openings the said bolts extending longitudinally of the frame and having their heads 14 bearing against the outer face of plate 9 (Fig. 5).

Serial No. 688,152.

A spring 15 encircles each bolt, bearing at one end against the outer face of plate 10 and at the other against a washer 16. A nut 17 engages each bolt adjacent to the Washer.

An opening 18 is provided in the upper side of the pressing chamber at approximately the longitudinal center of the frame, and inclined deflecting or guide boards 19 are arranged at the sides of the opening. A plunger is provided in the chamber for pressing the hay, and the said plunger comprises a head 20 and a shank 21.

A shaft 22 is arranged transversely of the plunger near the junction of shank and head, and the ends of the shaft extend laterally through slots or guide openings 23 in the side walls of the chamber. An L- shaped or angle plate is arranged at each side of each slot or guide opening, and each plate consists of a portion 2 1 secured to the outer face of the side wall of the chamber by bolts o-r rivets 26 and a portion 25 ex tending laterally from the said wall.

The portions 25 of the plates at each slot or opening are parallel and form a track or guideway for a roller 27 on the shaft. The slots or openings are horizontal and straight for the greater portion of their length, but near their outer ends the said slots or openings are curved downwardly, the concavity of the curve being upwardly, and the plates 24.25 follow the curve of the slots (Fig. 1).

The ends of shaft 22 are extended beyond the side walls of the pressing chamber, and each end of the shaft 22 has a link 28 pivoted thereon. Each link has its opposite end pivoted to one end of a lever 29, whose opposite end is pivoted to a wrist pin 30 on a gear wheel 31 secured to the adjacent end of a shaft 32, arranged transversely of the chamber and journaled in bearings 33 in the side walls of the chamber.

Each gear wheel 31 meshes with a pinion 34; on the adjacent end of a counter shaft 35, journaled in bearings 36 on the bars 1, and provided intermediate its ends with a gear wheel ,37. The gear wheel 37 meshes with a pinion 38 on a driving shaft 39, j ournaled in bearings 40 in the side walls of the chamber, and provided at one end With a pulley'tl for the engagement of a belt from any suitable motor.

Each of the levers 29 before mentioned is pivoted intermediate its ends, and nearer the link 28 than the wrist pin 30, to the adjacent end of a shaft 42, and the said shaft is arranged transversely of the pressing chamber in the slots or openings 23, and is provided with Wheels 43 engaging the guide or trackway formed by the angle plates 2425 before mentioned.

When the driving shaft-39 is rotated the levers 29 once during each rotation of shaft 32 will be swung on the shaft 42 in such manner that the lower ends of the levers will be raised, thus moving the links 28 int-o a more nearly horizontal position and causing them to move the plunger toward the opening 18 of the chamber.

The shaft 22 must follow the guide or trackway, on account of the wheels 27, and shafts 22 and 42 will move in the said guide or trackways toward the opening 18 until the wrist pin 30 begins to move away from the said opening. The plunger is thus reciprocated once for each complete rotation of shaft 32. The gearing between driving shaft 39 and shaft 32 is a reducing gear, so that shaft 39 rotates at a much lower speed than shaft 32.

The material to be pressed, as, for instance, hay, is fed through opening 18, and is compressed against a plurality of series of trips 44, one of the series being arranged at each side of the pressing chamber. Each trip is pivoted at one end ona rod 45 arranged in vertical position just outside the chamber. -A second rod 46 is arranged adjacent to each rod 45, and each trip is recessed on its inner side to receive the said rod.

The rods are passed through a plate 47 on the under side of the chamber along the outer face of the side wall of the chamber and through the horizontal portion 48 of an angle plate whose vertical port-ion 49 extends upwardly at the rear of opening 18. Each trip arm has a lateral lug 50 which extends through an opening 51 in the cham ber wall into position for engagement by the material as it is pressed.

A lever 52 is pivoted at 53 at each side of the chamber at the rear end of opening 18, and a roller 54 is arranged transversely of the chamber below the rear end of the opening 18, the roller having t-runnions 55 passing through arc-shaped slots 56 in the side walls and engaging the rear ends of the levers 52. Each lever 52 has a vertically perforated lug 57 at its forward end.

A rod 58 has one of its ends passed through the perforation of the lug, and a spring 59 encircles each rod between the lug and a head 60 on the lower end of the rod pivoted to the plate 24-25 adjacent to the lever. The roller may thus move upwardly as the bale increases in size, but is normally pressed toward the lower ends of slots 56 by the springs.

The plates 3 closing in the sides and top of the baling or pressing chamber extend only to the junction between the bars 1 and extensions 1, and the space between the extensions 1 and the lower bars 2 is open, to permit access to the bale for the placing of wires. As the bale is pressed toward the yoke 44*, the extensions 1 may move longitudinally away from the bars 1 and also upwardly to some extent away from the bars 2 against the resistance of springs 15. The said parts swing on the yoke or bail, and the nuts 7 may be turned to vary the pressure exerted by the bail.

The arrangement of the operating mechanism for the plunger permits powerful leverage and a consequent increase in elliciency, together with a long pressing stroke and a very quick return of the plunger.
